Most programmable Motorolas allow you to
program below 146 by holding the shift key down while entering the frequency you want.
You MUST release the shift key when you enter the decimal point.
You MUST fill the entire field -use zeros (while holding down shift).
When you are done, hit enter like normal, and the frequency you entered will appear in regular decimal like any other frequency.
I got this from here, they are a wealth of info.http://www.batlabs.com/
